Trivial unless it fails

[packit-as-a-service]

Cockpit tests failed for commit 05f1502. @martinpitt, @jelly, @mvollmer please check.

Probably an anomalous failure for us...would be nice to improve test framework to give us a bit more, though.

We should be retrying on the problem below:

                                   ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

    raise DPClientInvocationError(
dbus_python_client_gen._errors.DPClientInvocationError: Error while getting value for property "Devnode" belonging to interface "org.storage.stratis3.blockdev.r7"

not failing, since it is almost certainly just caused by not getting object paths on the D-Bus quite fast enough.

We expect the tests to pass.
